Billionaire Warren Buffett sent his first tweet on Thursday, picking up more than 45,000 followers in just under 45 minutes.

The handle was not officially verified by Twitter, but was confirmed by Fortune magazine, which hosted Buffett for a live webcast Thursday. It was billed as the first social media event for the notoriously technology-averse billionaire.

By joining Twitter, the Berkshire Hathaway Inc chief executive officer now stands in good mogul company. Other relatively recent converts to the service include News Corp CEO Rupert Murdoch (@RupertMurdoch) and former U.S. President Bill Clinton (@BillClinton).
